(question) Don't you get that info in

select * from pg_user;

or using the view pg_stat_activity:

select * from pg_stat_activity;

Added:

the view says:

One row per server process, showing database OID, database name, process ID, user OID, user name, current query, query's waiting status, time at which the current query began execution, time at which the process was started, and client's address and port number. The columns that report data on the current query are available unless the parameter stats_command_string has been turned off. Furthermore, these columns are only visible if the user examining the view is a superuser or the same as the user owning the process being reported on.

can't you filter and get that information? that will be the current users on the Database, you can use began execution time to get all queries from last 5 minutes for example...

something like that.

From git reset

"pull" or "merge" always leaves the original tip of the current branch in ORIG_HEAD.

git reset --hard ORIG_HEAD

Resetting hard to it brings your index file and the working tree back to that state, and resets the tip of the branch to that commit.

git reset --merge ORIG_HEAD

After inspecting the result of the merge, you may find that the change in the other branch is unsatisfactory. Running "git reset --hard ORIG_HEAD" will let you go back to where you were, but it will discard your local changes, which you do not want. "git reset --merge" keeps your local changes.

Before any patches are applied, ORIG_HEAD is set to the tip of the current branch.
This is useful if you have problems with multiple commits, like running 'git am' on the wrong branch or an error in the commits that is more easily fixed by changing the mailbox (e.g. +errors in the "From:" lines).

In addition, merge always sets '.git/ORIG_HEAD' to the original state of HEAD so a problematic merge can be removed by using 'git reset ORIG_HEAD'.

Note: from here

HEAD is a moving pointer. Sometimes it means the current branch, sometimes it doesn't.

So HEAD is NOT a synonym for "current branch" everywhere already.

HEAD means "current" everywhere in git, but it does not necessarily mean "current branch" (i.e. detached HEAD).

But it almost always means the "current commit".
It is the commit "git commit" builds on top of, and "git diff --cached" and "git status" compare against.
It means the current branch only in very limited contexts (exactly when we want a branch name to operate on --- resetting and growing the branch tip via commit/rebase/etc.).

Reflog is a vehicle to go back in time and time machines have interesting interaction with the notion of "current".

HEAD@{5.minutes.ago} could mean "dereference HEAD symref to find out what branch we are on RIGHT NOW, and then find out where the tip of that branch was 5 minutes ago".
Alternatively it could mean "what is the commit I would have referred to as HEAD 5 minutes ago, e.g. if I did "git show HEAD" back then".

git1.8.4 (July 2013) introduces introduced a new notation!
(Actually, it will be for 1.8.5, Q4 2013: reintroduced with commit 9ba89f4), by Felipe Contreras.

Instead of typing four capital letters "HEAD", you can say "@" now,
e.g. "git log @".

See commit cdfd948

Typing 'HEAD' is tedious, especially when we can use '@' instead.

The reason for choosing '@' is that it follows naturally from the ref@op syntax (e.g. HEAD@{u}), except we have no ref, and no operation, and when we don't have those, it makes sens to assume 'HEAD'.

So now we can use 'git show @~1', and all that goody goodness.

Until now '@' was a valid name, but it conflicts with this idea, so let's make it invalid. Probably very few people, if any, used this name.

There's probably a limit set in your webserver. Some browsers/proxies will also implement a timeout. Invoking long running processes via an HTTP request is just plain silly. The right way to solve the problem (assuming you can't make the processing any faster) is to use the HTTP request to trigger processing outside of the webserver session group then poll the status via HTTP until you've got a result set.

Git 1.7.2 introduced the ability to cherry pick a range of commits. From the release notes:

git cherry-pick learned to pick a range of commits (e.g. cherry-pick A..B and cherry-pick --stdin), so did git revert; these do not support the nicer sequencing control rebase [-i] has, though.

To cherry-pick all the commits from commit A to commit B (where A is older than B), run:

git cherry-pick A^..B

If you want to ignore A itself, run:

git cherry-pick A..B

Just execute

sudo npm i --save

That's all

There are 3 things you need.

1. You need to oAuth with the owner of those photos. (with the 'user_photos' extended permission)

2. You need the access token (which you get returned in the URL box after the oAuth is done.)

3. When those are complete you can then access the photos like so https://graph.facebook.com/me?access_token=ACCESS_TOKEN

You can find all of the information in more detail here: http://developers.facebook.com/docs/authentication

The syntax is

pid_t waitpid(pid_t pid, int *statusPtr, int options);

1.where pid is the process of the child it should wait.

2.statusPtr is a pointer to the location where status information for the terminating process is to be stored.

3.specifies optional actions for the waitpid function. Either of the following option flags may be specified, or they can be combined with a bitwise inclusive OR operator:

WNOHANG WUNTRACED WCONTINUED

If successful, waitpid returns the process ID of the terminated process whose status was reported. If unsuccessful, a -1 is returned.

benifits over wait

1.Waitpid can used when you have more than one child for the process and you want to wait for particular child to get its execution done before parent resumes

2.waitpid supports job control

3.it supports non blocking of the parent process

I had the same issue for two days now. Disabled SELinux and everything but nothing helped. And I realize it just may not be smart to disable security for a small fix. Then I came upon this article - http://wiki.centos.org/HowTos/SELinux/ that explains how SELinux operates. So this is what I did and it fixed my problem.

1. Enable access to your main phpmyadmin directory by going to parent directory of phpmyadmin (mine was html) and typing:

   chcon -v --type=httpd_sys_content_t phpmyadmin
   

2. Now do the same for the index.php by typing:

   chcon -v --type=httpd_sys_content_t phpmyadmin/index.php
   

   Now go back and check if you are getting a blank page. If you are, then you are on the right track. If not, go back and check your httpd.config directory settings. Once you do get the blank page with no warnings, proceed.

3. Now recurse through all the files in your phpmyadmin directory by running:

   chron -Rv --type=httpd_sys_content_t phpmyadmin/*
   

Go back to your phpmyadmin page and see if you are seeing what you need. If you are running a web server that's accessible from outside your network, make sure that you reset your SELinux to the proper security level. Hope this helps!

sc.nextLine() is better as compared to parsing the input. Because performance wise it will be good.

Two and a half years late is better than never, right?

int System.in.read() reads the next byte of data from the input stream. But I am sure you already knew that, because it is trivial to look up. So, what you are probably asking is:

• Why is it declared to return an int when the documentation says that it reads a byte?

• and why does it appear to return garbage? (I type '9', but it returns 57.)

It returns an int because besides all the possible values of a byte, it also needs to be able to return an extra value to indicate end-of-stream. So, it has to return a type which can express more values than a byte can.

^{Note: They could have made it a short, but they opted for int instead, possibly as a tip of the hat of historical significance to C, whose getc() function also returns an int, but more importantly because short is a bit cumbersome to work with, (the language offers no means of specifying a short literal, so you have to specify an int literal and cast it to short,) plus on certain architectures int has better performance than short.}

It appears to return garbage because when you view a character as an integer, what you are looking at is the ASCII^(*) value of that character. So, a '9' appears as a 57. But if you cast it to a character, you get '9', so all is well.

^{Think of it this way: if you typed the character '9' it is nonsensical to expect System.in.read() to return the number 9, because then what number would you expect it to return if you had typed an 'a'? Obviously, characters must be mapped to numbers. ASCII(*) is a system of mapping characters to numbers. And in this system, character '9' maps to number 57, not number 9.}

(*) Not necessarily ASCII; it may be some other encoding, like UTF-16; but in the vast majority of encodings, and certainly in all popular encodings, the first 127 values are the same as ASCII. And this includes all english alphanumeric characters and popular symbols.

By design, getRequestURL() gives you the full URL, missing only the query string.

In HttpServletRequest, you can get individual parts of the URI using the methods below:

// Example: http://myhost:8080/people?lastname=Fox&age=30

String uri = request.getScheme() + "://" +   // "http" + "://
             request.getServerName() +       // "myhost"
             ":" +                           // ":"
             request.getServerPort() +       // "8080"
             request.getRequestURI() +       // "/people"
             "?" +                           // "?"
             request.getQueryString();       // "lastname=Fox&age=30"

• .getScheme() will give you "https" if it was a https://domain request.
• .getServerName() gives domain on http(s)://domain.
• .getServerPort() will give you the port.

Use the snippet below:

String uri = request.getScheme() + "://" +
             request.getServerName() + 
             ("http".equals(request.getScheme()) && request.getServerPort() == 80 || "https".equals(request.getScheme()) && request.getServerPort() == 443 ? "" : ":" + request.getServerPort() ) +
             request.getRequestURI() +
            (request.getQueryString() != null ? "?" + request.getQueryString() : "");

This snippet above will get the full URI, hiding the port if the default one was used, and not adding the "?" and the query string if the latter was not provided.

Proxied requests

Note, that if your request passes through a proxy, you need to look at the X-Forwarded-Proto header since the scheme might be altered:

request.getHeader("X-Forwarded-Proto")

Also, a common header is X-Forwarded-For, which show the original request IP instead of the proxys IP.

request.getHeader("X-Forwarded-For")

If you are responsible for the configuration of the proxy/load balancer yourself, you need to ensure that these headers are set upon forwarding.

if you build an MVC project, its included by default. otherwise, what Nick said.

module Selenium
  module WebDriver
    class Element
      def select(value)
        self.find_elements(:tag_name => "option").find do |option|
          if option.text == value
            option.click
              return
           end
       end
    end

and you will be able to select value:

browser.find_element(:xpath, ".//xpath").select("Value")

Now there's no need to side load any packages of execute any scripts to get the Play Store on the emulator. Starting from Android Studio 2.4 now you can create an AVD that has Play Store pre-installed on it. Currently it is supported only on the AVDs running Android 7.0 (API 24) system images.

Note: Compatible devices are denoted by the new Play Store column.

Another mysteriously unknown RDBMS. Your Syntax is perfectly fine in PostgreSQL. Other query styles may perform faster (especially the NOT EXISTS variant or a LEFT JOIN), but your query is perfectly legit.

Be aware of pitfalls with NOT IN, though, when involving any NULL values:

• Find records where join doesn't exist

Variant with LEFT JOIN:

SELECT *
FROM   friend f
LEFT   JOIN likes l USING (id1, id2)
WHERE  l.id1 IS NULL;

See @Michal's answer for the NOT EXISTS variant.
A more detailed assessment of four basic variants:

• Select rows which are not present in other table

Be aware that there are some issues where System#nanoTime() cannot be reliably used on multi-core CPU's to record elapsed time ... each core has maintains its own TSC (Time Stamp Counter): this counter is used to obtain the nano time (really it is the number of ticks since the CPU booted).

Hence, unless the OS does some TSC time warping to keep the cores in sync, then if a thread gets scheduled on one core when the initial time reading is taken, then switched to a different core, the relative time can sporadically appear to jump backwards and forwards.

I observed this some time ago on AMD/Solaris where elapsed times between two timing points were sometimes coming back as either negative values or unexpectedly large positive numbers. There was a Solaris kernel patch and a BIOS setting required to force the AMD PowerNow! off, which appeared to solved it.

Also, there is (AFAIK) a so-far unfixed bug when using java System#nanoTime() in a VirtualBox environment; causing all sorts of bizarre intermittent threading problems for us as much of the java.util.concurrency package relies on nano time.

Is System.nanoTime() completely useless? http://vbox.innotek.de/pipermail/vbox-trac/2010-January/135631.html

NumPy 1.7.0 (when numpy.pad was added) is pretty old now (it was released in 2013) so even though the question asked for a way without using that function I thought it could be useful to know how that could be achieved using numpy.pad.

It's actually pretty simple:

>>> import numpy as np
>>> a = np.array([[ 1.,  1.,  1.,  1.,  1.],
...               [ 1.,  1.,  1.,  1.,  1.],
...               [ 1.,  1.,  1.,  1.,  1.]])
>>> np.pad(a, [(0, 1), (0, 1)], mode='constant')
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

In this case I used that 0 is the default value for mode='constant'. But it could also be specified by passing it in explicitly:

>>> np.pad(a, [(0, 1), (0, 1)], mode='constant', constant_values=0)
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

Just in case the second argument ([(0, 1), (0, 1)]) seems confusing: Each list item (in this case tuple) corresponds to a dimension and item therein represents the padding before (first element) and after (second element). So:

[(0, 1), (0, 1)]
         ^^^^^^------ padding for second dimension
 ^^^^^^-------------- padding for first dimension

  ^------------------ no padding at the beginning of the first axis
     ^--------------- pad with one "value" at the end of the first axis.

In this case the padding for the first and second axis are identical, so one could also just pass in the 2-tuple:

>>> np.pad(a, (0, 1), mode='constant')
array([[ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.]])

In case the padding before and after is identical one could even omit the tuple (not applicable in this case though):

>>> np.pad(a, 1, mode='constant')
array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.]])

Or if the padding before and after is identical but different for the axis, you could also omit the second argument in the inner tuples:

>>> np.pad(a, [(1, ), (2, )], mode='constant')
array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.]])

However I tend to prefer to always use the explicit one, because it's just to easy to make mistakes (when NumPys expectations differ from your intentions):

>>> np.pad(a, [1, 2], mode='constant')
array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  1.,  1.,  1.,  1.,  1.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.],
       [ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.]])

Here NumPy thinks you wanted to pad all axis with 1 element before and 2 elements after each axis! Even if you intended it to pad with 1 element in axis 1 and 2 elements for axis 2.

I used lists of tuples for the padding, note that this is just "my convention", you could also use lists of lists or tuples of tuples, or even tuples of arrays. NumPy just checks the length of the argument (or if it doesn't have a length) and the length of each item (or if it has a length)!

just to add another solution, particularly useful if you are using the new pandas assessors, other solutions will replace the original pandas and lose the assessors

df.drop(df.loc[df['line_race']==0].index, inplace=True)

This should do the trick.....

reset($array);
while (list($elementKey, $element) = each($array)) {
    while (list($key, $value2) = each($element)) {
        if($key == 'id' && $value == 'searched_value') {
            unset($array[$elementKey]);
        }
    }
}

You don't need to be echoing the info within the php file. A php include will automatically include any HTML within that file.

Make sure you're actually using a index file with a .php extension, .html won't work with php includes. (Unless you're telling your server to treat .html files otherwise)

Make sure your paths are correctly set up. From your description, the way you've set it up your header.php/navbar.php/image.php files should be in your root directory. So your root directory should look like this:

index.php
navbar.php
image.php
header.php

Otherwise if those PHP files are in a folder called /includes/, it should look like so:

<?php include ('includes/headings.php'); ?>

textBox1.Text = "Line1\r\r\Line2";
Solved the problem.

I trained a neural network in Keras to perform non linear regression on some data. This is some part of my code for testing on new data using previously saved model configuration and weights.

fname = r"C:\Users\tauseef\Desktop\keras\tutorials\BestWeights.hdf5"
modelConfig = joblib.load('modelConfig.pkl')
recreatedModel = Sequential.from_config(modelConfig)
recreatedModel.load_weights(fname)
unseenTestData = np.genfromtxt(r"C:\Users\tauseef\Desktop\keras\arrayOf100Rows257Columns.txt",delimiter=" ")
X_test = unseenTestData
standard_scalerX = StandardScaler()
standard_scalerX.fit(X_test)
X_test_std = standard_scalerX.transform(X_test)
X_test_std = X_test_std.astype('float32')
unseenData_predictions = recreatedModel.predict(X_test_std)

Just test if the array is empty.

$.getJSON(url,function(json){
    if ( json.length == 0 ) {
        console.log("NO DATA!")
    }
});

I could resolve this problem in Kotlin with help of @JacksonProperty annotation. Usage example for above case would be:

import com.fasterxml.jackson.annotation.JsonProperty

To do links, you can do

.social h2 a:link {
  color: pink;
  font-size: 14px;   
}

You can change the hover, visited, and active link styling too. Just replace "link" with what you want to style. You can learn more at the w3schools page CSS Links.

In addition to @csgillespie's answer, segments is also vectorised to help with this sort of thing:

plot (x, y, ylim=c(0,6))
segments(x,y-sd,x,y+sd)
epsilon <- 0.02
segments(x-epsilon,y-sd,x+epsilon,y-sd)
segments(x-epsilon,y+sd,x+epsilon,y+sd)

You map your dispatcher on *.do:

<servlet-mapping>
   <servlet-name>Dispatcher</servlet-name>
   <url-pattern>*.do</url-pattern>
</servlet-mapping>

but your controller is mapped on an url without .do:

@RequestMapping("/editPresPage")

Try changing this to:

@RequestMapping("/editPresPage.do")

Use the "onto" option:

git rebase --onto master^ D^ D

Update in July 2020:

During the last 16 months, maybe the most notable change in the React community is React hooks.

According to what I observe, in order to gain better compatibility with functional components and hooks, projects (even those large ones) would tend to use:

1. hook + async thunk (hook makes everything very flexible so you could actually place async thunk in where you want and use it as normal functions, for example, still write thunk in action.ts and then useDispatch() to trigger the thunk: https://stackoverflow.com/a/59991104/5256695),
2. useRequest,
3. GraphQL/Apollo useQuery useMutation
4. react-fetching-library
5. other popular choices of data fetching/API call libraries, tools, design patterns, etc

In comparison, redux-saga doesn't really provide significant benefit in most normal cases of API calls comparing to the above approaches for now, while increasing project complexity by introducing many saga files/generators (also because the last release v1.1.1 of redux-saga was on 18 Sep 2019, which was a long time ago).

But still, redux-saga provides some unique features such as racing effect and parallel requests. Therefore, if you need these special functionalities, redux-saga is still a good choice.

Original post in March 2019:

Just some personal experience:

1. For coding style and readability, one of the most significant advantages of using redux-saga in the past is to avoid callback hell in redux-thunk — one does not need to use many nesting then/catch anymore. But now with the popularity of async/await thunk, one could also write async code in sync style when using redux-thunk, which may be regarded as an improvement in redux-thunk.

2. One may need to write much more boilerplate codes when using redux-saga, especially in Typescript. For example, if one wants to implement a fetch async function, the data and error handling could be directly performed in one thunk unit in action.js with one single FETCH action. But in redux-saga, one may need to define FETCH_START, FETCH_SUCCESS and FETCH_FAILURE actions and all their related type-checks, because one of the features in redux-saga is to use this kind of rich “token” mechanism to create effects and instruct redux store for easy testing. Of course one could write a saga without using these actions, but that would make it similar to a thunk.

3. In terms of the file structure, redux-saga seems to be more explicit in many cases. One could easily find an async related code in every sagas.ts, but in redux-thunk, one would need to see it in actions.

4. Easy testing may be another weighted feature in redux-saga. This is truly convenient. But one thing that needs to be clarified is that redux-saga “call” test would not perform actual API call in testing, thus one would need to specify the sample result for the steps which may be used after the API call. Therefore before writing in redux-saga, it would be better to plan a saga and its corresponding sagas.spec.ts in detail.

5. Redux-saga also provides many advanced features such as running tasks in parallel, concurrency helpers like takeLatest/takeEvery, fork/spawn, which are far more powerful than thunks.

In conclusion, personally, I would like to say: in many normal cases and small to medium size apps, go with async/await style redux-thunk. It would save you many boilerplate codes/actions/typedefs, and you would not need to switch around many different sagas.ts and maintain a specific sagas tree. But if you are developing a large app with much complex async logic and the need for features like concurrency/parallel pattern, or have a high demand for testing and maintenance (especially in test-driven development), redux-sagas would possibly save your life.

Anyway, redux-saga is not more difficult and complex than redux itself, and it does not have a so-called steep learning curve because it has well-limited core concepts and APIs. Spending a small amount of time learning redux-saga may benefit yourself one day in the future.

You can try this from the console:

adb logcat --buffer=crash 

More info on this option:

adb logcat --help

...

  -b <buffer>, --buffer=<buffer>         Request alternate ring buffer, 'main',
                  'system', 'radio', 'events', 'crash', 'default' or 'all'.
                  Multiple -b parameters or comma separated list of buffers are
                  allowed. Buffers interleaved. Default -b main,system,crash.

Basically this is what you need to do:
in the first activity:

Intent intent = new Intent();
intent.setAction(this, SecondActivity.class);
intent.putExtra(tag, value);
startActivity(intent);

and in the second activtiy:

Intent intent = getIntent();
intent.getBooleanExtra(tag, defaultValue);
intent.getStringExtra(tag, defaultValue);
intent.getIntegerExtra(tag, defaultValue);

one of the get-functions will give return you the value, depending on the datatype you are passing through.

You need to set a height on the DIV. Otherwise it will keep expanding indefinitely.

Save it as a .ps1 file and then execute

powershell -file "path\to your\start stop nation service command file.ps1"

thought I would add this for any future peeps. It will always make sure that its monday if needed, can also be used to always ensure sunday. For me I always need monday, but local is dependant on the machine being used, and this is an easy fix:

var begin = moment().isoWeekday(1).startOf('week');
var begin2 = moment().startOf('week');
// could check to see if day 1 = Sunday  then add 1 day
// my mac on bst still treats day 1 as sunday    

var firstDay = moment().startOf('week').format('dddd') === 'Sunday' ?     
moment().startOf('week').add('d',1).format('dddd DD-MM-YYYY') : 
moment().startOf('week').format('dddd DD-MM-YYYY');

document.body.innerHTML = '<b>could be monday or sunday depending on client: </b><br />' + 
begin.format('dddd DD-MM-YYYY') + 
'<br /><br /> <b>should be monday:</b> <br>' + firstDay + 
'<br><br> <b>could also be sunday or monday </b><br> ' + 
begin2.format('dddd DD-MM-YYYY');

Sometime you must to give all the link like this

System.Web.HttpContext.Current.Request.UrlReferrer.ToString();

(in option when "Current" not founded)

WinSCP can be called from batch file:

"C:\Program Files\WinSCP\WinSCP.exe" /console

Example commands:

option batch on 
option confirm off  
option transfer binary 
open sftp://username@hostname:port -hostkey="ssh-rsa " 

Choose one you need:

>>> s = "Rajasekar SP  def"
>>> s.split(' ')
['Rajasekar', 'SP', '', 'def']
>>> s.split()
['Rajasekar', 'SP', 'def']
>>> s.partition(' ')
('Rajasekar', ' ', 'SP  def')

str.split and str.partition

Consider this as your select list:

<select onchange="var optionVal = $(this).find(':selected').val(); doSomething(optionVal)">

                                <option value="mostSeen">Most Seen</option>
                                <option value="newst">Newest</option>
                                <option value="mostSell">Most Sell</option>
                                <option value="mostCheap">Most Cheap</option>
                                <option value="mostExpensive">Most Expensive</option>

                            </select>

then you check selected option like this:

function doSomething(param) {

    if ($(param.selected)) {
        alert(param + ' is selected!');
    }

}

There aren't a lot of them because they would be in competition with JFreeChart, and it's awesome. You can get documentation and examples by downloading the developer's guide. There are also tons of free online tutorials if you search for them.

Trying ?max, you'll see that it actually has a na.rm = argument, set by default to FALSE. (That's the common default for many other R functions, including sum(), mean(), etc.)

Setting na.rm=TRUE does just what you're asking for:

d <- c(1, 100, NA, 10)
max(d, na.rm=TRUE)

If you do want to remove all of the NAs, use this idiom instead:

d <- d[!is.na(d)]

A final note: Other functions (e.g. table(), lm(), and sort()) have NA-related arguments that use different names (and offer different options). So if NA's cause you problems in a function call, it's worth checking for a built-in solution among the function's arguments. I've found there's usually one already there.

If you only have access to the view object, then you can get the parameters defined in the URL path this way:

view.kwargs.get('url_param')

If you only have access to the request object, use the following:

request.resolver_match.kwargs.get('url_param')

Tested on Django 3.

Should you try this class Map:

var myMap = new Map();_x000D_
_x000D_
// setting the values_x000D_
myMap.set("1", 'value1');_x000D_
myMap.set("2", 'value2');_x000D_
myMap.set("3", 'value3');_x000D_
_x000D_
myMap.size; // 3_x000D_
_x000D_
// getting the values_x000D_
myMap.get("1");    // "value associated with "value1"_x000D_
myMap.get("2");       // "value associated with "value1"_x000D_
myMap.get("3");      // "value associated with "value3"

If you just want to disable right click for saving images on the web page, go with this CSS solution:

Tested working in both Chrome and Firefox.

Use this code:

$this->db->where(['id'=>2])->from("table name")->count_all_results();

or

$this->db->from("table name")->count_all_results();

Python 2.6 and 3 specifically say to avoid using PIPE for stdout and stderr.

The correct way is

import subprocess

# must create a file object to store the output. Here we are getting
# the ssid we are connected to
outfile = open('/tmp/ssid', 'w');
status = subprocess.Popen(["iwgetid"], bufsize=0, stdout=outfile)
outfile.close()

# now operate on the file

I know this thread is old, but for others who encounter the same problem, that implement @Brad8118 solution (which i prefer, because if you choose to make the input readonly then the user will not be able to delete the date value inserted from datepicker if he chooses) and also need to prevent the user from pasting a value (as @ErikPhilips suggested to be needed), I let this addition here, which worked for me: $("#my_txtbox").bind('paste',function(e) { e.preventDefault(); //disable paste }); from here https://www.dotnettricks.com/learn/jquery/disable-cut-copy-and-paste-in-textbox-using-jquery-javascript and the whole specific script used by me (using fengyuanchen/datepicker plugin instead):

$('[data-toggle="datepicker"]').datepicker({
    autoHide: true,
    pick: function (e) {
        e.preventDefault();
        $(this).val($(this).datepicker('getDate', true));
    }
}).keypress(function(event) {
    event.preventDefault(); // prevent keyboard writing but allowing value deletion
}).bind('paste',function(e) {
    e.preventDefault()
}); //disable paste;

try this

 final Spinner cardStatusSpinner1 = (Spinner) findViewById(R.id.text_interested);
    String cardStatusString;
    cardStatusSpinner1.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> parent,
                View view, int pos, long id) {
            cardStatusString = parent.getItemAtPosition(pos).toString();
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

 final Button saveBtn = (Button) findViewById(R.id.save_button);
    saveBtn .setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub

            System.out.println("Selected cardStatusString : " + cardStatusString ); //this will print the result
        }
    });

xxd -p file

Or if you want it all on a single line:

xxd -p file | tr -d '\n'

This would print the files in those directories line by line.

array=(ww/* ee/* qq/*)
printf "%s\n" "${array[@]}"

E0_copy is not a deep copy. You don't make a deep copy using list() (Both list(...) and testList[:] are shallow copies).

You use copy.deepcopy(...) for deep copying a list.

deepcopy(x, memo=None, _nil=[])
    Deep copy operation on arbitrary Python objects.

See the following snippet -

>>> a = [[1, 2, 3], [4, 5, 6]]
>>> b = list(a)
>>> a
[[1, 2, 3], [4, 5, 6]]
>>> b
[[1, 2, 3], [4, 5, 6]]
>>> a[0][1] = 10
>>> a
[[1, 10, 3], [4, 5, 6]]
>>> b   # b changes too -> Not a deepcopy.
[[1, 10, 3], [4, 5, 6]]

Now see the deepcopy operation

>>> import copy
>>> b = copy.deepcopy(a)
>>> a
[[1, 10, 3], [4, 5, 6]]
>>> b
[[1, 10, 3], [4, 5, 6]]
>>> a[0][1] = 9
>>> a
[[1, 9, 3], [4, 5, 6]]
>>> b    # b doesn't change -> Deep Copy
[[1, 10, 3], [4, 5, 6]]

I don't think anyone has explained here that one issue is that you need "member pointers" rather than normal function pointers.

Member pointers to functions are not simply function pointers. In implementation terms, the compiler cannot use a simple function address because, in general, you don't know the address to call until you know which object to dereference for (think virtual functions). You also need to know the object in order to provide the this implicit parameter, of course.

Having said that you need them, now I'll say that you really need to avoid them. Seriously, member pointers are a pain. It is much more sane to look at object-oriented design patterns that achieve the same goal, or to use a boost::function or whatever as mentioned above - assuming you get to make that choice, that is.

If you are supplying that function pointer to existing code, so you really need a simple function pointer, you should write a function as a static member of the class. A static member function doesn't understand this, so you'll need to pass the object in as an explicit parameter. There was once a not-that-unusual idiom along these lines for working with old C code that needs function pointers

class myclass
{
  public:
    virtual void myrealmethod () = 0;

    static void myfunction (myclass *p);
}

void myclass::myfunction (myclass *p)
{
  p->myrealmethod ();
}

Since myfunction is really just a normal function (scope issues aside), a function pointer can be found in the normal C way.

EDIT - this kind of method is called a "class method" or a "static member function". The main difference from a non-member function is that, if you reference it from outside the class, you must specify the scope using the :: scope resolution operator. For example, to get the function pointer, use &myclass::myfunction and to call it use myclass::myfunction (arg);.

This kind of thing is fairly common when using the old Win32 APIs, which were originally designed for C rather than C++. Of course in that case, the parameter is normally LPARAM or similar rather than a pointer, and some casting is needed.

this works well for me

    arglen=$#
    argparam=$*
    if [ $arglen -eq '3' ];
    then
            echo Valid Number of arguments
            echo "Arguments are $*"
    else
            echo only four arguments are allowed
    fi

The below code always gives the public IP of the client (and not a private IP behind a proxy).

from flask import request

if request.environ.get('HTTP_X_FORWARDED_FOR') is None:
    print(request.environ['REMOTE_ADDR'])
else:
    print(request.environ['HTTP_X_FORWARDED_FOR']) # if behind a proxy

That's simple. It's explained in man bash:

/bin/bash
       The bash executable
/etc/profile
       The systemwide initialization file, executed for login shells
~/.bash_profile
       The personal initialization file, executed for login shells
~/.bashrc
       The individual per-interactive-shell startup file
~/.bash_logout
       The individual login shell cleanup file, executed when a login shell exits
~/.inputrc
       Individual readline initialization file

Login shells are the ones that are read one you login (so, they are not executed when merely starting up xterm, for example). There are other ways to login. For example using an X display manager. Those have other ways to read and export environment variables at login time.

Also read the INVOCATION chapter in the manual. It says "The following paragraphs describe how bash executes its startup files.", i think that's a spot-on :) It explains what an "interactive" shell is too.

Bash does not know about .environment. I suspect that's a file of your distribution, to set environment variables independent of the shell that you drive.

$files = glob($_SERVER["DOCUMENT_ROOT"]."/myFolder/*");

I think your sample is saving to your project folders and unless the default iis, or .NET , user has create permission then it won't be able to create the logs folder.

I'd create the logs folder first and allow the iis user full permission and see if the log file is being created.

In my case I set Diagnostic for the MSBuild verbosity as shown here.

Guess what... in the last line of the Output window in Visual Studio it showed this:

2>"C:\Company\Project\project.sharded\Project\Project.csproj" (Rebuild;BuiltProjectOutputGroup;BuiltProjectOutputGroupDependencies;DebugSymbolsProjectOutputGroup;DebugSymbolsProjectOutputGroupDependencies;DocumentationProjectOutputGroup;DocumentationProjectOutputGroupDependencies;SatelliteDllsProjectOutputGroup;SatelliteDllsProjectOutputGroupDependencies;SGenFilesOutputGroup;SGenFilesOutputGroupDependencies target) (1) ->

2>
2>    2147 Warning(s)
2>    1 Error(s)

This looks like a bug in Visual Studio 2019 (16.3.5).

No errors were shown in the Error List window in Visual Studio.

This is the kind of errors that generally appear in the Error List window.

This is the offending line:

var sut = _sdb.SysUsableThreads.SingleOrDefault(sut => sut.uid == thread.uid && sut.thread_core == thread.core);

OK. Can't use sut because the var is named sut and I named the lambda sut. Again, this is the kind of thing that should be displayed in the Error List. For sure this is a bug in Visual Studio 2019. I reported it inside Visual Studio.

I was looking for in place solution to this problem. This solves the purpose in O(k).

def solution(self, list, k):
    r=len(list)-1
    i = 0
    while i<k:
        temp = list[0]
        list[0:r] = list[1:r+1]
        list[r] = temp
        i+=1
    return list

This is the most important thing to know about the Tuple type. Tuple is a class, not a struct. It thus will be allocated upon the managed heap. Each class instance that is allocated adds to the burden of garbage collection.

Note: The properties Item1, Item2, and further do not have setters. You cannot assign them. The Tuple is immutable once created in memory.

It seems you have found your solution, but still it will be helpful to others, on this page on point based on Chrome 59.

4.Note the red triangle in the top-right of the Animation Frame Fired event. Whenever you see a red triangle, it's a warning that there may be an issue related to this event.

If you hover on these triangle you can see those are the violation handler errors and as per point 4. yes there is some issue related to that event.

I found that I can run this command:

notepad $((Split-Path $profile -Parent) + "\profile.ps1")

and it opens my default powershell profile (at least when using Terminal for Windows). I found that here.

Then add an alias. For example, here is my alias of jn for jupyter notebook (I hate typing out the cumbersome jupyter notebook every time):

Set-Alias -Name jn -Value C:\Users\words\Anaconda3\Scripts\jupyter-notebook.exe

Arrays are better in performance. ArrayList provides additional functionality such as "remove" at the cost of performance.

Add -confirm:$false to suppress confirmation.

Thanks for the answers above, that helped me a lot :-) But for those (like me) forced to still support Android 1.5 we can use java reflection for backward compatible:

Configuration conf = getResources().getConfiguration();
int screenLayout = 1; // application default behavior
try {
    Field field = conf.getClass().getDeclaredField("screenLayout");
    screenLayout = field.getInt(conf);
} catch (Exception e) {
    // NoSuchFieldException or related stuff
}
// Configuration.SCREENLAYOUT_SIZE_MASK == 15
int screenType = screenLayout & 15;
// Configuration.SCREENLAYOUT_SIZE_SMALL == 1
// Configuration.SCREENLAYOUT_SIZE_NORMAL == 2
// Configuration.SCREENLAYOUT_SIZE_LARGE == 3
// Configuration.SCREENLAYOUT_SIZE_XLARGE == 4
if (screenType == 1) {
    ...
} else if (screenType == 2) {
    ...
} else if (screenType == 3) {
    ...
} else if (screenType == 4) {
    ...
} else { // undefined
    ...
}

there you go

date('d.m.Y',strtotime("-1 days"));

this will work also if month change

If you want to uninstall when connected to single device/emulator then use below command

adb uninstall <package name>

else with multiple devices then use below command

adb -s <device ID> uninstall <package name>

Prevent Screen Rotation just add this following line in your Manifests.

<activity
        android:name=".YourActivity"
        android:screenOrientation="portrait" />

This works for me.

Write code on xml file.

<Button android:width="wrap_content"
        android:height="wrap_content"
        android:id="@+id/button"
        android:text="Click"/>

Write Code in your java file

Button button=(Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            startActivity(new Intent(getApplicationContext(),Secondclass.class));
           /* if you want to finish the first activity then just call
            finish(); */
        }
    });

There is a built-in library called pickle. Using pickle you can dump objects to a file and load them later.

import pickle

f = open('store.pckl', 'wb')
pickle.dump(obj, f)
f.close()

f = open('store.pckl', 'rb')
obj = pickle.load(f)
f.close()

you must change Territory and click on save, after one minute your app will be available. No need to Remove from sale

Try if this works for you. This works on FF, IE8+ and chrome. The else part applies for non-firefox browsers. Though this gives you a zoom effect, it does not actually modify the zoom value at browser level.

    var currFFZoom = 1;
    var currIEZoom = 100;

    $('#plusBtn').on('click',function(){
        if ($.browser.mozilla){
            var step = 0.02;
            currFFZoom += step; 
            $('body').css('MozTransform','scale(' + currFFZoom + ')');
        } else {
            var step = 2;
            currIEZoom += step;
            $('body').css('zoom', ' ' + currIEZoom + '%');
        }
    });

    $('#minusBtn').on('click',function(){
        if ($.browser.mozilla){
            var step = 0.02;
            currFFZoom -= step;                 
            $('body').css('MozTransform','scale(' + currFFZoom + ')');

        } else {
            var step = 2;
            currIEZoom -= step;
            $('body').css('zoom', ' ' + currIEZoom + '%');
        }
    });

I would re-write the original target test, taking care the needed variable is defined IN THE SAME SUB-PROCESS as the application to launch:

test:
    ( NODE_ENV=test mocha --harmony --reporter spec test )

double roundTwoDecimals(double d) {
  DecimalFormat twoDForm = new DecimalFormat("#.##");
  return Double.valueOf(twoDForm.format(d));
}

You can use the following CSS to center the form (note that it is important to set the width to something that isn´t 'auto' for this to work):

form {
   margin-left:auto;
   margin-right:auto;
   width:100px;
}

<select>_x000D_
    <option value="" style="display:none">Choose one provider</option>_x000D_
    <option value="1">One</option>_x000D_
    <option value="2">Two</option>_x000D_
</select>

This way the user cannot see this option, but it shows in the select box.

I think I found exactly what you need. It may help others.

You can use the method UrlEncodedFormEntity.writeTo(OutputStream).

UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(nvp); 
http.connect();

OutputStream output = null;
try {
  output = http.getOutputStream();    
  formEntity.writeTo(output);
} finally {
 if (output != null) try { output.close(); } catch (IOException ioe) {}
}

First you have to include the file you call:

#!/bin/bash
. includes/included_file.sh

then you call your function like this:

#!/bin/bash
my_called_function

You have probably installed Eclipse for Java Developers instead of Eclipse IDE for Enterprise Java Developers, server tab and some other are not available.

You don't have to uninstall. Just rerun eclipse-inst-win64.exe and choose Java EE IDE

I had the same issue for one of my branch.

These commands work for me.

git fetch --all
git checkout <branch-name>

The result in isEmailValid can be used to test whether the email's syntax is valid.

var validEmailRegEx = /^[A-Z0-9_'%=+!`#~$*?^{}&|-]+([\.][A-Z0-9_'%=+!`#~$*?^{}&|-]+)*@[A-Z0-9-]+(\.[A-Z0-9-]+)+$/i
var isEmailValid = validEmailRegEx.test("Email To Test");

If the variable table contains invalid characters (like a space) you should add square brackets around the variable.

public DataTable fillDataTable(string table)
{
    string query = "SELECT * FROM dstut.dbo.[" + table + "]";

    using(SqlConnection sqlConn = new SqlConnection(conSTR))
    using(SqlCommand cmd = new SqlCommand(query, sqlConn))
    {
        sqlConn.Open();
        DataTable dt = new DataTable();
        dt.Load(cmd.ExecuteReader());
        return dt;
    }
}

By the way, be very careful with this kind of code because is open to Sql Injection. I hope for you that the table name doesn't come from user input

You could use Kernel#test:

test ?d, 'some directory'

it gets it's origins from https://ss64.com/bash/test.html you will notice bash test has this flag -d to test if a directory exists -d file True if file is a Directory. [[ -d demofile ]]

For those who Google for this error and arrive here: there might be another reason for receiving it. Eclipse gives this error when you have project setup - system configuration mismatch.

For example, if you import Java 1.7 project to Eclipse and you do not have 1.7 correctly set up then you will get this error. Then you can either go to Project - Preference - Java - Compiler and switch to 1.6 or earlier; or go to Window - Preferences - Java - Installed JREs and add/fix your JRE 1.7 installation.

I created a category for UIApplication with visibleViewControllers property. The main idea is pretty simple. I swizzled viewDidAppear and viewDidDisappear methods in UIViewController. In viewDidAppear method viewController is added to stack. In viewDidDisappear method viewController is removed from stack. NSPointerArray is used instead of NSArray to store weak UIViewController’s references . This approach works for any viewControllers hierarchy.

I usually like a StringBuilder when I'm working with MailMessage. Adding new lines is easy (via the AppendLine method), and you can simply set the Message's Body equal to StringBuilder.ToString() (... for the instance of StringBuilder).

StringBuilder result = new StringBuilder("my content here...");
result.AppendLine(); // break line

This C# function uses a regular expression to evaluate whether the passed email address is syntactically valid or not.

public static bool isValidEmail(string inputEmail)

Instead of using ->bindParam() you can pass the data only at the time of ->execute():

$data = [   ':item_name' => $_POST['item_name'],   ':item_type' => $_POST['item_type'],   ':item_price' => $_POST['item_price'],   ':item_description' => $_POST['item_description'],   ':image_location' => 'images/'.$_FILES['file']['name'],   ':status' => 0,   ':id' => 0, ];  $stmt->execute($data); 

In this way you would know exactly what values are going to be sent.

result() returns Object type data. . . . result_array() returns Associative Array type data.

You can use rand($min, $max) for that exact purpose.

In order to limit the values to values with x digits you can use the following:

$x = 3; // Amount of digits
$min = pow(10,$x);
$max = pow(10,$x+1)-1);
$value = rand($min, $max);

You can try this

$i = 1
echo '<p class="paragraph'.$i.'"></p>';
++i; 

Let's get pedantic, because there are differences that can actually affect your code's behavior. Much of the following is taken from comments made to an "Old New Thing" article.

Sometimes the memory returned by the new operator will be initialized, and sometimes it won't depending on whether the type you're newing up is a POD (plain old data), or if it's a class that contains POD members and is using a compiler-generated default constructor.

• In C++1998 there are 2 types of initialization: zero and default
• In C++2003 a 3rd type of initialization, value initialization was added.

Assume:

struct A { int m; }; // POD
struct B { ~B(); int m; }; // non-POD, compiler generated default ctor
struct C { C() : m() {}; ~C(); int m; }; // non-POD, default-initialising m

In a C++98 compiler, the following should occur:

• new A - indeterminate value

• new A() - zero-initialize

• new B - default construct (B::m is uninitialized)

• new B() - default construct (B::m is uninitialized)

• new C - default construct (C::m is zero-initialized)

• new C() - default construct (C::m is zero-initialized)

In a C++03 conformant compiler, things should work like so:

• new A - indeterminate value

• new A() - value-initialize A, which is zero-initialization since it's a POD.

• new B - default-initializes (leaves B::m uninitialized)

• new B() - value-initializes B which zero-initializes all fields since its default ctor is compiler generated as opposed to user-defined.

• new C - default-initializes C, which calls the default ctor.

• new C() - value-initializes C, which calls the default ctor.

So in all versions of C++ there's a difference between new A and new A() because A is a POD.

And there's a difference in behavior between C++98 and C++03 for the case new B().

This is one of the dusty corners of C++ that can drive you crazy. When constructing an object, sometimes you want/need the parens, sometimes you absolutely cannot have them, and sometimes it doesn't matter.

In case someone is still looking for something like this, I found that this new library called modin can help. It uses distributed computing that can help with the read. Here's a nice article comparing its functionality with pandas. It essentially uses the same functions as pandas.

import modin.pandas as pd
pd.read_csv(CSV_FILE_NAME)

Heuristic, in a nutshell is an "Educated guess". Wikipedia explains it nicely. At the end, a "general acceptance" method is taken as an optimal solution to the specified problem.

Heuristic is an adjective for experience-based techniques that help in problem solving, learning and discovery. A heuristic method is used to rapidly come to a solution that is hoped to be close to the best possible answer, or 'optimal solution'. Heuristics are "rules of thumb", educated guesses, intuitive judgments or simply common sense. A heuristic is a general way of solving a problem. Heuristics as a noun is another name for heuristic methods.

In more precise terms, heuristics stand for strategies using readily accessible, though loosely applicable, information to control problem solving in human beings and machines.

While an algorithm is a method containing finite set of instructions used to solving a problem. The method has been proven mathematically or scientifically to work for the problem. There are formal methods and proofs.

Heuristic algorithm is an algorithm that is able to produce an acceptable solution to a problem in many practical scenarios, in the fashion of a general heuristic, but for which there is no formal proof of its correctness.

As recommended by the Tensorflow GPU guide.

# Place tensors on the CPU
with tf.device('/CPU:0'):
  a = tf.constant([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])
  b = tf.constant([[1.0, 2.0], [3.0, 4.0], [5.0, 6.0]])
  # Any additional tf code placed in this block will be executed on the CPU

I didn't find it listed so updating the list.

You need to have the apk installed and running in front on your phone for this solution:

Windows CMD line:

adb shell dumpsys window windows | findstr <any unique string from your pkg Name>

Linux Terminal:

adb shell dumpsys window windows | grep -i <any unique string from your Pkg Name>

OUTPUT for Calculator package would be:

Window #7 Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}:

    mOwnerUid=10036 mShowToOwnerOnly=true package=com.android.calculator2 appop=NONE

    mToken=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

    mRootToken=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

    mAppToken=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

    WindowStateAnimator{3e160d22 com.android.calculator2/com.android.calculator2.Calculator}:

      mSurface=Surface(name=com.android.calculator2/com.android.calculator2.Calculator)

  mCurrentFocus=Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}

  mFocusedApp=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}

Main part is, First Line:

Window #7 Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}:

First part of the output is package name:

com.android.calculator2

Second Part of output (which is after /) can be two things, in our case its:

com.android.calculator2.Calculator

1. <PKg name>.<activity name> = <com.android.calculator2>.<Calculator>

   so .Calculator is our activity

2. If second part is entirely different from Package name and doesn't seem to contain pkg name which was before / in out output, then entire second part can be used as main activity.

To well understand the behaviour, you can run this code:

#include <iostream>

class MyClass
{
  public:
    MyClass() { std::cout << "run constructor MyClass::MyClass()" << std::endl; }
    ~MyClass() { std::cout << "run destructor MyClass::~MyClass()" << std::endl; }
    MyClass(const MyClass& x) { std::cout << "run copy constructor MyClass::MyClass(const MyClass&)" << std::endl; }
    MyClass& operator = (const MyClass& x) { std::cout << "run assignation MyClass::operator=(const MyClass&)" << std::endl; }
};

MyClass my_function()
{
  std::cout << "run my_function()" << std::endl;
  MyClass a;
  std::cout << "my_function is going to return a..." << std::endl;
  return a;
}

int main(int argc, char** argv)
{
  MyClass b = my_function();

  MyClass c;
  c = my_function();

  return 0;
}

The output is the following:

run my_function()
run constructor MyClass::MyClass()
my_function is going to return a...
run constructor MyClass::MyClass()
run my_function()
run constructor MyClass::MyClass()
my_function is going to return a...
run assignation MyClass::operator=(const MyClass&)
run destructor MyClass::~MyClass()
run destructor MyClass::~MyClass()
run destructor MyClass::~MyClass()

Note that this example was provided in C++03 context, it could be improved for C++ >= 11

To delete last 4 lines:

$ nl -b a file | sort -k1,1nr | sed '1, 4 d' | sort -k1,1n | sed 's/^ *[0-9]*\t//'   

You can use the following list as quick reference:

   /   = Root directory
   .   = This location
   ..  = Up a directory
   ./  = Current directory
   ../ = Parent of current directory
   ../../ = Two directories backwards

Use the SQLCMD utility.

http://technet.microsoft.com/en-us/library/ms162773.aspx

There is a connect statement that allows you to swing from database server A to server B in the same batch.

:Connect server_name[\instance_name] [-l timeout] [-U user_name [-P password]] Connects to an instance of SQL Server. Also closes the current connection.

On the other hand, if you are familiar with PowerShell, you can programmatic do the same.

From http://en.wikipedia.org/wiki/CDATA:

Since it is useful to be able to use less-than signs (<) and ampersands (&) in web page scripts, and to a lesser extent styles, without having to remember to escape them, it is common to use CDATA markers around the text of inline and elements in XHTML documents. But so that the document can also be parsed by HTML parsers, which do not recognise the CDATA markers, the CDATA markers are usually commented-out, as in this JavaScript example:

<script type="text/javascript">
//<![CDATA[
document.write("<");
//]]>
</script>

So it would become:

List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
while(true)
    Iterator<Integer> myListIterator = myCoords.iterator(); 
    while (myListIterator.hasNext()) {
        Integer coord = myListIterator.next();    
        System.out.print("\r" + coord);
        try{
    Thread.sleep(2000);
  }catch(Exception e){
   // handle the exception...
  }
    }
}

There's an ELSE in the DOS batch language? Back in the days when I did more of this kinda thing, there wasn't.

If my theory is correct and your ELSE is being ignored, you may be better off doing

IF NOT EXIST file GOTO label

...which will also save you a line of code (the one right after your IF).

Second, I vaguely remember some kind of bug with testing for the existence of directories. Life would be easier if you could test for the existence of a file in that directory. If there's no file you can be sure of, something to try (this used to work up to Win95, IIRC) would be to append the device file name NUL to your directory name, e.g.

IF NOT EXIST C:\dir\NUL GOTO ...

Use this also

NSString *ChkStr = [MyString substringWithRange:NSMakeRange(5, 26)];

Note - Your NSMakeRange(start, end) should be NSMakeRange(start, end- start);

In my case, it was the attachment size limit that causes the issue. Check and increase the size limit of mail worked for me.

str=str.replace(/^\s+|\s+$/g,'');

if you use .Values while creating the matrix X and Y vectors it will fix the problem.

y=dataset.iloc[:, 4].values

X=dataset.iloc[:, 0:4].values

when you use .Values it creates a Object representation of the created matrix will be returned with the axes removed. Check the below link for more information

To export db rather it is SQLITE or ROOM:

Firstly, add this permission in AndroidManifest.xml file:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Secondly, we drive to code the db functions:

private void exportDB() {
    try {
        File dbFile = new File(this.getDatabasePath(DATABASE_NAME).getAbsolutePath());
        FileInputStream fis = new FileInputStream(dbFile);

        String outFileName = DirectoryName + File.separator +
                DATABASE_NAME + ".db";

        // Open the empty db as the output stream
        OutputStream output = new FileOutputStream(outFileName);

        // Transfer bytes from the inputfile to the outputfile
        byte[] buffer = new byte[1024];
        int length;
        while ((length = fis.read(buffer)) > 0) {
            output.write(buffer, 0, length);
        }
        // Close the streams
        output.flush();
        output.close();
        fis.close();


    } catch (IOException e) {
        Log.e("dbBackup:", e.getMessage());
    }
}

        if (success) {
            exportDB();
        }
    } else {
        Toast.makeText(this, "Not create folder", Toast.LENGTH_SHORT).show();
    }

}

Assign the DATABASE_NAME without .db extension and its data type is string

@Pantelis answer somehow steered me to a solution for a similar misunderstanding. A message board project I'm working on needs to show an optional image. I was having fits trying to get the src=imagefile to concatenate a fixed path and variable filename string until I saw the quirky use of "''" quotes :-)

<template id="symp-tmpl">
  <div>
    <div v-for="item in items" style="clear: both;">
      <div v-if="(item.imagefile !== '[none]')">
        <img v-bind:src="'/storage/userimages/' + item.imagefile">
      </div>
      sub: <span>@{{ item.subject }}</span>
      <span v-if="(login == item.author)">[edit]</span>
      <br>@{{ item.author }}
      <br>msg: <span>@{{ item.message }}</span>
    </div>
  </div>
</template>

Adding into this: it depends on what your array is defined as. Consider:

dim a() as integer
dim b() as string
dim c() as variant

'these doesn't work
if isempty(a) then msgbox "integer arrays can be empty"
if isempty(b) then msgbox "string arrays can be empty"

'this is because isempty can only be tested on classes which have an .empty property

'this do work
if isempty(c) then msgbox "variants can be empty"

So, what can we do? In VBA, we can see if we can trigger an error and somehow handle it, for example

dim a() as integer
dim bEmpty as boolean

bempty=false

on error resume next
bempty=not isnumeric(ubound(a))
on error goto 0

But this is really clumsy... A nicer solution is to declare a boolean variable (a public or module level is best). When the array is first initialised, then set this variable. Because it's a variable declared at the same time, if it loses it's value, then you know that you need to reinitialise your array. However, if it is initialised, then all you're doing is checking the value of a boolean, which is low cost. It depends on whether being low cost matters, and if you're going to be needing to check it often.

option explicit

'declared at module level
dim a() as integer
dim aInitialised as boolean

sub DoSomethingWithA()
if not aInitialised then InitialiseA
'you can now proceed confident that a() is intialised
end sub

sub InitialiseA()
'insert code to do whatever is required to initialise A
'e.g. 
redim a(10)
a(1)=123
'...
aInitialised=true
end sub

The last thing you can do is create a function; which in this case will need to be dependent on the clumsy on error method.

function isInitialised(byref a() as variant) as boolean
isInitialised=false
on error resume next
isinitialised=isnumeric(ubound(a))
end function

ListView.FocusedItem.Index 

or you can use foreach loop like this

int index= -1;
foreach (ListViewItem itm in listView1.SelectedItems)
{
    if (itm.Selected)
    {
        index= itm.Index;
    }
}

Parameters take input before arguments. What you should do instead is add a parameter that accepts an array, and make it the first position parameter. ex:

param(
    [Parameter(Position = 0)]
    [string[]]$Hosts,
    [string]$VLAN
    )

foreach ($i in $Hosts)  
{ 
    Do-Stuff $i
}

Then call it like:

.\script.ps1 host1, host2, host3 -VLAN 2

Notice the comma between the values. This collects them in an array

Swift 3 Bonus: Why didn't anyone mention the short form?

CGRect(origin: .zero, size: size)

.zero instead of CGPoint.zero

When the type is defined, you can safely omit it.

attr_accessor is a Ruby method that makes a getter and a setter. attr_accessible is a Rails method that allows you to pass in values to a mass assignment: new(attrs) or update_attributes(attrs).

Here's a mass assignment:

Order.new({ :type => 'Corn', :quantity => 6 })

You can imagine that the order might also have a discount code, say :price_off. If you don't tag :price_off as attr_accessible you stop malicious code from being able to do like so:

Order.new({ :type => 'Corn', :quantity => 6, :price_off => 30 })

Even if your form doesn't have a field for :price_off, if it's in your model it's available by default. This means a crafted POST could still set it. Using attr_accessible white lists those things that can be mass assigned.

You can simply return if you want to skip the current iteration.

Since you're in a function, if you return before doing anything else, then you have effectively skipped execution of the code below the return statement.

with your own soup object:

soup.p.next_sibling.strip()

1. you grab the <p> directly with soup.p *(this hinges on it being the first <p> in the parse tree)
2. then use next_sibling on the tag object that soup.p returns since the desired text is nested at the same level of the parse tree as the <p>
3. .strip() is just a Python str method to remove leading and trailing whitespace

*otherwise just find the element using your choice of filter(s)

in the interpreter this looks something like:

In [4]: soup.p
Out[4]: <p>something</p>

In [5]: type(soup.p)
Out[5]: bs4.element.Tag

In [6]: soup.p.next_sibling
Out[6]: u'\n      THIS IS MY TEXT\n      '

In [7]: type(soup.p.next_sibling)
Out[7]: bs4.element.NavigableString

In [8]: soup.p.next_sibling.strip()
Out[8]: u'THIS IS MY TEXT'

In [9]: type(soup.p.next_sibling.strip())
Out[9]: unicode

@robertc has it right, but you also need to notice that svg, #container causes the svg to be scaled exponentially for anything but 100% (once for #container and once for svg).

In other words, if I applied 50% h/w to both elements, it's actually 50% of 50%, or .5 * .5, which equals .25, or 25% scale.

One selector works fine when used as @robertc suggests.

svg {
  width:50%;
  height:50%;
}

The best approach for the specific case here, in my opinion, is the one commonpike suggested. A little improvement I'd suggest that works in modern browsers is:

// aao is the "associative array" you need to "sort"
Object.keys(aao).sort(function(a,b){return aao[b]-aao[a]});

This could apply easily and work great in the specific case here so you can do:

let aoo={};
aao["sub2"]=1;
aao["sub0"]=-1;
aao["sub1"]=0;
aao["sub3"]=1;
aao["sub4"]=0;

let sk=Object.keys(aao).sort(function(a,b){return aao[b]-aao[a]});

// now you can loop using the sorted keys in `sk` to do stuffs
for (let i=sk.length-1;i>=0;--i){
 // do something with sk[i] or aoo[sk[i]]
}

Besides of this, I provide here a more "generic" function you can use to sort even in wider range of situations and that mixes the improvement I just suggested with the approaches of the answers by Ben Blank (sorting also string values) and PopeJohnPaulII (sorting by specific object field/property) and lets you decide if you want an ascendant or descendant order, here it is:

// aao := is the "associative array" you need to "sort"
// comp := is the "field" you want to compare or "" if you have no "fields" and simply need to compare values
// intVal := must be false if you need comparing non-integer values
// desc := set to true will sort keys in descendant order (default sort order is ascendant)
function sortedKeys(aao,comp="",intVal=false,desc=false){
  let keys=Object.keys(aao);
  if (comp!="") {
    if (intVal) {
      if (desc) return keys.sort(function(a,b){return aao[b][comp]-aao[a][comp]});
      else return keys.sort(function(a,b){return aao[a][comp]-aao[a][comp]});
    } else {
      if (desc) return keys.sort(function(a,b){return aao[b][comp]<aao[a][comp]?1:aao[b][comp]>aao[a][comp]?-1:0});
      else return keys.sort(function(a,b){return aao[a][comp]<aao[b][comp]?1:aao[a][comp]>aao[b][comp]?-1:0});
    }
  } else {
    if (intVal) {
      if (desc) return keys.sort(function(a,b){return aao[b]-aao[a]});
      else return keys.sort(function(a,b){return aao[a]-aao[b]});
    } else {
      if (desc) return keys.sort(function(a,b){return aao[b]<aao[a]?1:aao[b]>aao[a]?-1:0});
      else return keys.sort(function(a,b){return aao[a]<aao[b]?1:aao[a]>aao[b]?-1:0});
    }
  }
}

You can test the functionalities trying something like the following code:

let items={};
items['Edward']=21;
items['Sharpe']=37;
items['And']=45;
items['The']=-12;
items['Magnetic']=13;
items['Zeros']=37;
//equivalent to:
//let items={"Edward": 21, "Sharpe": 37, "And": 45, "The": -12, ...};

console.log("1: "+sortedKeys(items));
console.log("2: "+sortedKeys(items,"",false,true));
console.log("3: "+sortedKeys(items,"",true,false));
console.log("4: "+sortedKeys(items,"",true,true));
/* OUTPUT
1: And,Sharpe,Zeros,Edward,Magnetic,The
2: The,Magnetic,Edward,Sharpe,Zeros,And
3: The,Magnetic,Edward,Sharpe,Zeros,And
4: And,Sharpe,Zeros,Edward,Magnetic,The
*/

items={};
items['k1']={name:'Edward',value:21};
items['k2']={name:'Sharpe',value:37};
items['k3']={name:'And',value:45};
items['k4']={name:'The',value:-12};
items['k5']={name:'Magnetic',value:13};
items['k6']={name:'Zeros',value:37};

console.log("1: "+sortedKeys(items,"name"));
console.log("2: "+sortedKeys(items,"name",false,true));
/* OUTPUT
1: k6,k4,k2,k5,k1,k3
2: k3,k1,k5,k2,k4,k6
*/

As I already said, you can loop over sorted keys if you need doing stuffs

let sk=sortedKeys(aoo);
// now you can loop using the sorted keys in `sk` to do stuffs
for (let i=sk.length-1;i>=0;--i){
 // do something with sk[i] or aoo[sk[i]]
}

Last, but not least, some useful references to Object.keys and Array.sort

Use the sizing utility classes...

• h-100 = height 100%

Columns("A:E").Select

Can be directly replaced by

Columns(1).Resize(, 5).EntireColumn.Select

Where 1 can be replaced by a variable

n = 5
Columns(n).Resize(, n+4).EntireColumn.Select

In my opinion you are best dealing with a block of columns rather than looping through columns n to n + 4 as it is more efficient.

In addition, using select will slow your code down. So instead of selecting your columns and then performing an action on the selection try instead to perform the action directly. Below is an example to change the colour of columns A-E to yellow.

Columns(1).Resize(, 5).EntireColumn.Interior.Color = 65535

No, you can't insert into multiple tables in one MySQL command. You can however use transactions.

BEGIN;
INSERT INTO users (username, password)
  VALUES('test', 'test');
INSERT INTO profiles (userid, bio, homepage) 
  VALUES(LAST_INSERT_ID(),'Hello world!', 'http://www.stackoverflow.com');
COMMIT;

Have a look at LAST_INSERT_ID() to reuse autoincrement values.

Edit: you said "After all this time trying to figure it out, it still doesn't work. Can't I simply put the just generated ID in a $var and put that $var in all the MySQL commands?"

Let me elaborate: there are 3 possible ways here:

1. In the code you see above. This does it all in MySQL, and the LAST_INSERT_ID() in the second statement will automatically be the value of the autoincrement-column that was inserted in the first statement.

   Unfortunately, when the second statement itself inserts rows in a table with an auto-increment column, the LAST_INSERT_ID() will be updated to that of table 2, and not table 1. If you still need that of table 1 afterwards, we will have to store it in a variable. This leads us to ways 2 and 3:

2. Will stock the LAST_INSERT_ID() in a MySQL variable:

   INSERT ...
   SELECT LAST_INSERT_ID() INTO @mysql_variable_here;
   INSERT INTO table2 (@mysql_variable_here, ...);
   INSERT INTO table3 (@mysql_variable_here, ...);
   

3. Will stock the LAST_INSERT_ID() in a php variable (or any language that can connect to a database, of your choice):

   • INSERT ...
   • Use your language to retrieve the LAST_INSERT_ID(), either by executing that literal statement in MySQL, or using for example php's mysql_insert_id() which does that for you
   • INSERT [use your php variable here]

WARNING

Whatever way of solving this you choose, you must decide what should happen should the execution be interrupted between queries (for example, your database-server crashes). If you can live with "some have finished, others not", don't read on.

If however you decide "either all queries finish, or none finish - I do not want rows in some tables but no matching rows in others, I always want my database tables to be consistent", you need to wrap all statements in a transaction. That's why I used the BEGIN and COMMIT here.

Comment again if you need more info :)

In Jenkins 2.138.3 there are two different types of pipelines.

Declarative and Scripted pipelines.

"Declarative pipelines is a new extension of the pipeline DSL (it is basically a pipeline script with only one step, a pipeline step with arguments (called directives), these directives should follow a specific syntax. The point of this new format is that it is more strict and therefore should be easier for those new to pipelines, allow for graphical editing and much more. scripted pipelines is the fallback for advanced requirements."

jenkins pipeline: agent vs node?

Here is an example of using environment and global variables in a Declarative Pipeline. From what I can tell enviroment are static after they are set.

def  browser = 'Unknown'

pipeline {
    agent any
    environment {
    //Use Pipeline Utility Steps plugin to read information from pom.xml into env variables
    IMAGE = readMavenPom().getArtifactId()
    VERSION = readMavenPom().getVersion()


    }
    stages {
        stage('Example') {
            steps {
                script {
                    browser = sh(returnStdout: true, script: 'echo Chrome')
                }
            }
        }
        stage('SNAPSHOT') {
                when {
                    expression { 
                        return !env.JOB_NAME.equals("PROD") && !env.VERSION.contains("RELEASE")
                    }
                }
                steps {
                    echo "SNAPSHOT"
                    echo "${browser}"
                }
            }
            stage('RELEASE') {
                when {
                    expression { 
                        return !env.JOB_NAME.equals("TEST") && !env.VERSION.contains("RELEASE")
                    }
                }
                steps {
                    echo "RELEASE"
                    echo "${browser}"
                }
            }
    }//end of stages 
}//end of pipeline

There are some SMTP servers that work without authentication, but if the server requires authentication, there is no way to circumvent that.

PHP's built-in mail functions are very limited - specifying the SMTP server is possible in WIndows only. On *nix, mail() will use the OS's binaries.

If you want to send E-Mail to an arbitrary SMTP server on the net, consider using a library like SwiftMailer. That will enable you to use, for example, Google Mail's outgoing servers.

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {
                    JSONArray array=(JSONArray)resultObject;
                    for (Object object : array) {
                        JSONObject obj =(JSONObject)object;
                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));
                }

            } catch (Exception e) {
                // TODO: handle exception
            }

        } catch (IOException ex) {
        }
        return null;
    }
}

etc...

A little late to the party, but answers still took me time and foreign reads to understand this problem. So I want to summarize what I have find out about the Gemfile.lock.

When you are building a Rails App, you are using certain versions of gems in your local machine. If you want to avoid errors in the production mode and other branches, you have to use that one Gemfile.lock file everywhere and tell bundler to bundle for rebuilding gems every time it changes.

If Gemfile.lock has changed on your production machine and Git doesn't let you git pull, you should write git reset --hard to avoid that file change and write git pull again.

You are going to have to expose and endpoint (URL) in your system which will accept the POST request from the ajax call in jQuery.

Then, when processing that url from PHP, you would call your function and return the result in the appropriate format (JSON most likely, or XML if you prefer).

When we use crontab or the deprecated /etc/rc.local file, we need a delay (e.g. sleep 10, depending on the machine) to make sure that system services are available. Usually, systemd (or upstart) is used to manage which services start when the system boots. You can try use the similar configuration for this:

# /etc/systemd/system/docker-compose-app.service

[Unit]
Description=Docker Compose Application Service
Requires=docker.service
After=docker.service

[Service]
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/srv/docker
ExecStart=/usr/local/bin/docker-compose up -d
ExecStop=/usr/local/bin/docker-compose down
TimeoutStartSec=0

[Install]
WantedBy=multi-user.target

Or, if you want run without the -d flag:

# /etc/systemd/system/docker-compose-app.service

[Unit]
Description=Docker Compose Application Service
Requires=docker.service
After=docker.service

[Service]
WorkingDirectory=/srv/docker
ExecStart=/usr/local/bin/docker-compose up
ExecStop=/usr/local/bin/docker-compose down
TimeoutStartSec=0
Restart=on-failure
StartLimitIntervalSec=60
StartLimitBurst=3

[Install]
WantedBy=multi-user.target

Change the WorkingDirectory parameter with your dockerized project path. And enable the service to start automatically:

systemctl enable docker-compose-app

Well one solution could be:

list.get(list.size()-1)

Edit: You have to convert the collection to a list before maybe like this: new ArrayList(coll)

Here's the implementation in JOSM:

/**
 * Returns the Java version as an int value.
 * @return the Java version as an int value (8, 9, etc.)
 * @since 12130
 */
public static int getJavaVersion() {
    String version = System.getProperty("java.version");
    if (version.startsWith("1.")) {
        version = version.substring(2);
    }
    // Allow these formats:
    // 1.8.0_72-ea
    // 9-ea
    // 9
    // 9.0.1
    int dotPos = version.indexOf('.');
    int dashPos = version.indexOf('-');
    return Integer.parseInt(version.substring(0,
            dotPos > -1 ? dotPos : dashPos > -1 ? dashPos : 1));
}

You can define a context for your application say ExampleContext which will hold the context of your application and then use it to instantiate an activity like this:

var intent = new Intent(Application.ApplicationContext, typeof(Activity2));
intent.AddFlags(ActivityFlags.NewTask);
Application.ApplicationContext.StartActivity(intent);

Please bear in mind that this code is written in C# as I use MonoDroid, but I believe it is very similar to Java. For how to create an ApplicationContext look at this thread

This is how I made my Application Class

    [Application]
    public class Application : Android.App.Application, IApplication
    {
        public Application(IntPtr handle, JniHandleOwnership transfer) : base(handle, transfer)
        {

        }
        public object MyObject { get; set; }
    }

Another way of doing this in plain bash is making use of the rev command like this:

cat file | rev | cut -d" " -f1 | rev | tr -d "." | tr "\n" ","

Basically, you reverse the lines of the file, then split them with cut using space as the delimiter, take the first field that cut produces and then you reverse the token again, use tr -d to delete unwanted chars and tr again to replace newline chars with ,

Also, you can avoid the first cat by doing:

rev < file | cut -d" " -f1 | rev | tr -d "." | tr "\n" ","

One way to get this error is to forget to use the 'new' keyword when instantiating your Date in javascript like this:

> d = Date();
'Tue Mar 15 2016 20:05:53 GMT-0400 (EDT)'
> typeof(d);
'string'
> d.getFullYear();
TypeError: undefined is not a function

Had you used the 'new' keyword, it would have looked like this:

> el@defiant $ node
> d = new Date();
Tue Mar 15 2016 20:08:58 GMT-0400 (EDT)
> typeof(d);
'object'
> d.getFullYear(0);
2016

Another way to get that error is to accidentally re-instantiate a variable in javascript between when you set it and when you use it, like this:

el@defiant $ node
> d = new Date();
Tue Mar 15 2016 20:12:13 GMT-0400 (EDT)
> d.getFullYear();
2016
> d = 57 + 23;
80
> d.getFullYear();
TypeError: undefined is not a function

Use the which function:

A <- c('a','a','b','b','b')
B <- c(1,0,1,1,0)
d <- data.frame(A, B)

r <- with(d, which(B==0, arr.ind=TRUE))
newd <- d[-r, ]

Remove the required: true rule.

Demo: Fiddle

jQuery('.validatedForm').validate({
            rules : {
                password : {
                    minlength : 5
                },
                password_confirm : {
                    minlength : 5,
                    equalTo : "#password"
                }
            }

The accepted answer worked for me but it was unstable (sometimes clicks wouldn't regsiter) so I added an additional MOUSEEVENTF_LEFTUP . Then it was working reliably

import win32api, win32con
def click(x,y):
    win32api.SetCursorPos((x,y))
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP,x,y,0,0) 
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,x,y,0,0)
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP,x,y,0,0)
click(10,10)

for (var key in data) {
    alert("User " + data[key] + " is #" + key); // "User john is #234"
}

Just delete module-info.java at your Project Explorer tab.

This one is good example for Swift 4 about async:

DispatchQueue.global(qos: .background).async {
    // Background Thread
    DispatchQueue.main.async {
        // Run UI Updates or call completion block
    }
}

Setting this attribute to ObjectMapper instance works,

objectMapper.enable(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY);

The way to do this is near the top of the man page

grep -i -A 10 'error data'

There IS A POINT in introducing MAX_FILE_SIZE client side hidden form field.

php.ini can limit uploaded file size. So, while your script honors the limit imposed by php.ini, different HTML forms can further limit an uploaded file size. So, when uploading video, form may limit* maximum size to 10MB, and while uploading photos, forms may put a limit of just 1mb. And at the same time, the maximum limit can be set in php.ini to suppose 10mb to allow all this.

Although this is not a fool proof way of telling the server what to do, yet it can be helpful.

• HTML does'nt limit anything. It just forwards the server all form variable including MAX_FILE_SIZE and its value.

Hope it helped someone.

You must place the label after a caption in order to for label to store the table's number, not the chapter's number.

\begin{table}
\begin{tabular}{| p{5cm} | p{5cm} | p{5cm} |}
  -- cut --
\end{tabular}
\caption{My table}
\label{table:kysymys}
\end{table}

Table \ref{table:kysymys} on page \pageref{table:kysymys} refers to the ...

So multiply text values would end up in the query with single quotes around each I used =join(Parameters!Customer.Value,"','"). So after ".Value" that is comma, double-quote, single-quote, comma, single-quote, double-quote, close-bracket. simples :)

I believe the id accessors don't match the bean naming conventions and that's why the exception is thrown. They should be as follows:

public Integer getId() { return id; }    
public void setId(Integer i){ id= i; }

In the most recent release (v1.0, released in March 2016), you are now able to use VS Code as the default git commit/diff tool. Quoted from the documentations:

1. Make sure you can run code --help from the command line and you get help.

   • if you do not see help, please follow these steps:

     • Mac: Select Shell Command: Install 'Code' command in path from the Command Palette.

       • Command Palette is what pops up when you press shift + ? + P while inside VS Code. (shift + ctrl + P in Windows)
     • Windows: Make sure you selected Add to PATH during the installation.
     • Linux: Make sure you installed Code via our new .deb or .rpm packages.
2. From the command line, run git config --global core.editor "code --wait"

Now you can run git config --global -e and use VS Code as editor for configuring Git. Add the following to enable support for using VS Code as diff tool:

[diff]
    tool = default-difftool
[difftool "default-difftool"]
    cmd = code --wait --diff $LOCAL $REMOTE

This leverages the new --diff option you can pass to VS Code to compare two files side by side.

To summarize, here are some examples of where you can use Git with VS Code:

• git rebase HEAD~3 -i allows to interactive rebase using VS Code
• git commit allows to use VS Code for the commit message
• git add -p followed by e for interactive add
• git difftool <commit>^ <commit> allows to use VS Code as diff editor for changes

To change the font name use

  "font.face": "Liberation Mono"

in this file, in my case with ST3 Default.sublime-theme

I had the same exception when trying to run a headless ChromeDriver with a scheduled task on a windows server (unattended). What solved it for me is to run the task as the user "Administrators" (notice the S at the end). What I also did (I don't know if its relevant) is selected the "Any Connection" from the task "Conditions" tab.

In objective c you can use CGRectContainsPoint(yourview.frame, touchpoint)

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
UITouch* touch = [touches anyObject];
CGPoint touchpoint = [touch locationInView:self.view];
if( CGRectContainsPoint(yourview.frame, touchpoint) ) {

}else{

}}

In swift 3 yourview.frame.contains(touchpoint)

 override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    let touch:UITouch = touches.first!
    let touchpoint:CGPoint = touch.location(in: self.view)
    if wheel.frame.contains(touchpoint)  {

    }else{

    }

}

For the special case of existing Windows Forms applications:

There is a way - though I don't know how well it works.
It goes like this:
Take the Windows Forms implementation from Mono.
Port it to .NET Core or NetStandard.

Recompile your Windows Forms applications against the new System.Windows.Forms.
Fix anything that may be broken by .NET Core.
Pray that mono implements the parts you need flawlessly.
(If it doesn't, you can always stop praying, and send the Mono project a pull request with your fix/patch/feature.)

Here's my CoreFX Windows Forms repository:
https://github.com/ststeiger/System.CoreFX.Forms

Two ways to do that..

Option 1:

1.  Go to "Start" -> "Run".

2.  Write "CMD" and press on "Enter" key.

3.  Write the command "net statistics server" and press on "Enter" key.

4.  The line that start with "Statistics since …" provides the time that the server was up from.


  The command "net stats srv" can be use instead.

Option 2:

Uptime.exe Tool Allows You to Estimate Server Availability with Windows NT 4.0 SP4 or Higher

If you want to sum the digit of a number, one way to do it is using sum() + a generator expression:

sum(int(i) for i in str(155))

I modified a little your code using sum(), maybe you want to take a look at it:

birthday = raw_input("When is your birthday(mm/dd/yyyy)? ")
summ = sum(int(i) for i in birthday[0:2])
sumd = sum(int(i) for i in birthday[3:5])
sumy = sum(int(i) for i in birthday[6:10])
sumall = summ + sumd + sumy
print "The sum of your numbers is", sumall
sumln = sum(int(c) for c in str(sumall)))
print "Your lucky number is", sumln

Next is used to pass control to the next middleware function. If not the request will be left hanging or open.

You need to set cors header on server side where you are requesting data from. For example if your backend server is in Ruby on rails, use following code before sending back response. Same headers should be set for any backend server.

headers['Access-Control-Allow-Origin'] = '*'
headers['Access-Control-Allow-Methods'] = 'POST, PUT, DELETE, GET, OPTIONS'
headers['Access-Control-Request-Method'] = '*'
headers['Access-Control-Allow-Headers'] = 'Origin, X-Requested-With, Content-Type, Accept, Authorization'

Your best bet is to use

table.YourClass tr:hover td {
background-color: #FEFEFE;
}

Rows aren't fully support for background color but cells are, using the combination of :hover and the child element will yield the results you need.

In my view, With Expire Header, server can tell the client when my data would be stale, while with Etag, server would check the etag value for client' each request.

Class Assertions in org.junit.jupiter.api

Use:

public static void assertArrayEquals(int[] expected,
                                     int[] actual)

Do this:

<input type="button" name="test" id="test" value="RUN" /><br/>

<?php

function testfun()
{
   echo "Your test function on button click is working";
}
if(array_key_exists('test',$_POST)){
   testfun();
}
?>

Take a look at the domReady script that allows setting up of multiple functions to execute when the DOM has loaded. It's basically what the Dom ready does in many popular JavaScript libraries, but is lightweight and can be taken and added at the start of your external script file.

Example usage

// add reference to domReady script or place 
// contents of script before here

function codeAddress() {

}

domReady(codeAddress);

JodaTime is nice, however, for the sake of completeness and/or if you prefer API-provided facilities, here are the standard API approaches.

When starting off with java.util.Date instances like below:

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
Date startDate = formatter.parse("2010-12-20");
Date endDate = formatter.parse("2010-12-26");

Here's the legacy java.util.Calendar approach in case you aren't on Java8 yet:

Calendar start = Calendar.getInstance();
start.setTime(startDate);
Calendar end = Calendar.getInstance();
end.setTime(endDate);

for (Date date = start.getTime(); start.before(end); start.add(Calendar.DATE, 1), date = start.getTime()) {
    // Do your job here with `date`.
    System.out.println(date);
}

And here's Java8's java.time.LocalDate approach, basically exactly the JodaTime approach:

LocalDate start = startDate.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
LocalDate end = endDate.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();

for (LocalDate date = start; date.isBefore(end); date = date.plusDays(1)) {
    // Do your job here with `date`.
    System.out.println(date);
}

If you'd like to iterate inclusive the end date, then use !start.after(end) and !date.isAfter(end) respectively.

EncodeAndSend is not a static function, which means it can be called on an instance of the class CPMSifDlg. You cannot write this:

 CPMSifDlg::EncodeAndSend(/*...*/);  //wrong - EncodeAndSend is not static

It should rather be called as:

 CPMSifDlg dlg; //create instance, assuming it has default constructor!
 dlg.EncodeAndSend(/*...*/);   //correct 

Another option is to use a list comprehension:

df['First Season'] = [1 if year > 1990 else year for year in df['First Season']]

instead of

mySelect.toSource()

use

mySelect.val()

you can try this.

data_you_need=pd.DataFrame()
for infile in glob.glob("*.xlsx"):
    data = pandas.read_excel(infile)
    data_you_need=data_you_need.append(data,ignore_index=True)

I hope it can help.

Another way to do it:

Collections.addAll(collectionInstance,array);

The simple solution is to cast CLOB to BLOB and then request length of BLOB !

The problem is that Oracle doesn't have a function that cast CLOB to BLOB, but we can simply define a function to do that

create or replace
FUNCTION clob2blob (p_in clob) RETURN blob IS 
    v_blob        blob;
    v_desc_offset PLS_INTEGER := 1;
    v_src_offset  PLS_INTEGER := 1;
    v_lang        PLS_INTEGER := 0;
    v_warning     PLS_INTEGER := 0;  
BEGIN
    dbms_lob.createtemporary(v_blob,TRUE);
    dbms_lob.converttoblob
        ( v_blob
        , p_in
        , dbms_lob.getlength(p_in)
        , v_desc_offset
        , v_src_offset
        , dbms_lob.default_csid
        , v_lang
        , v_warning
        );
    RETURN v_blob;
END;

The SQL command to use to obtain number of bytes is

SELECT length(clob2blob(fieldname)) as nr_bytes 

or

SELECT dbms_lob.getlength(clob2blob(fieldname)) as nr_bytes

I have tested this on Oracle 10g without using Unicode(UTF-8). But I think that this solution must be correct using Unicode(UTF-8) Oracle instance :-)

I want render thanks to Nashev that has posted a solution to convert clob to blob How convert CLOB to BLOB in Oracle? and to this post written in german (the code is in PL/SQL) 13ter.info.blog that give additionally a function to convert blob to clob !

Can somebody test the 2 commands in Unicode(UTF-8) CLOB so I'm sure that this works with Unicode ?

I always find images helpful when learning a new concept, so this is a supplemental answer.

The %p means a percentage of the parent, that is, a percentage of the narrowest dimension of whatever view we set our drawable on. The images above were generated by changing the gradientRadius in this code

my_gradient_drawable

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <gradient
        android:type="radial"
        android:gradientRadius="10%p"
        android:startColor="#f6ee19"
        android:endColor="#115ede" />
</shape>

Which can be set on a view's background attribute like this

<View
    android:layout_width="200dp"
    android:layout_height="100dp"
    android:background="@drawable/my_gradient_drawable"/>

Center

You can change the center of the radius with

android:centerX="0.2"
android:centerY="0.7"

where the decimals are fractions of the width and height for x and y respectively.

Documentation

Here are some notes from the documentation explaining things a little more.

android:gradientRadius

Radius of the gradient, used only with radial gradient. May be an explicit dimension or a fractional value relative to the shape's minimum dimension.

May be a floating point value, such as "1.2".

May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

May be a fractional value, which is a floating point number appended with either % or %p, such as "14.5%". The % suffix always means a percentage of the base size; the optional %p suffix provides a size relative to some parent container.

In SQL Management Studio you can:

1. Right click on the result set grid, select 'Save Result As...' and save in.

2. On a tool bar toggle 'Result to Text' button. This will prompt for file name on each query run.

If you need to automate it, use bcp tool.

You could use a <span> instead of an <h1>.

Have a look at http://sqlite.org/lang_conflict.html.

You want something like:

insert or replace into Book (ID, Name, TypeID, Level, Seen) values
((select ID from Book where Name = "SearchName"), "SearchName", ...);

Note that any field not in the insert list will be set to NULL if the row already exists in the table. This is why there's a subselect for the ID column: In the replacement case the statement would set it to NULL and then a fresh ID would be allocated.

This approach can also be used if you want to leave particular field values alone if the row in the replacement case but set the field to NULL in the insert case.

For example, assuming you want to leave Seen alone:

insert or replace into Book (ID, Name, TypeID, Level, Seen) values (
   (select ID from Book where Name = "SearchName"),
   "SearchName",
    5,
    6,
    (select Seen from Book where Name = "SearchName"));

I've ported c# code used to work against smtp.google.com:587 to work via office365 without success. Tried all combinations of Credential before/after using Ssl and almost every recommendation made on the Internet - w/o success (got 5.7.1 .... error).

Finally got this line from somewhere as last resort, just before .Send(message)

smtpClient.TargetName = "STARTTLS/smtp.office365.com";

Since then - every send() is big success.

Swift

    // adjust place holder text
    let paddingView = UIView(frame: CGRectMake(0, 0, 10, usernameOrEmailField.frame.height))
    usernameOrEmailField.leftView = paddingView
    usernameOrEmailField.leftViewMode = UITextFieldViewMode.Always

The Merge method takes the values from the second table and merges them in with the first table, so the first will now hold the values from both.

If you want to preserve both of the original tables, you could copy the original first, then merge:

dtAll = dtOne.Copy();
dtAll.Merge(dtTwo);

// Solution to enter only numeric value in text box

$('#num_of_emp').keyup(function () { 
    this.value = this.value.replace(/[^0-9.]/g,'');
});

for an input box such as :

<input type='text' name='number_of_employee' id='num_of_emp' />

You aren't going to be able to do this from the HashMap class alone.

I would take the Map<String, String> codes, construct a reverse map of TreeMap<String, String> reversedMap where you map the values of the codes Map to the keys (this would require your original Map to have a one-to-one mapping from key-to-value). Since the TreeMap provides Iterators which returns entries in ascending key order, this will give you the value/key combination of the first map in the order (sorted by values) you desire.

Map<String, String> reversedMap = new TreeMap<String, String>(codes);

//then you just access the reversedMap however you like...
for (Map.Entry entry : reversedMap.entrySet()) {
    System.out.println(entry.getKey() + ", " + entry.getValue());
}

There are several collections libraries (commons-collections, Google Collections, etc) which have similar bidirectional Map implementations.

You could use the built-in module pprint (https://docs.python.org/3.9/library/pprint.html).

How you can read the file with json data and print it out.

import json
import pprint

json_data = None
with open('file_name.txt', 'r') as f:
    data = f.read()
    json_data = json.loads(data)

pprint.pprint(json_data)

I solve a similar problem.

• connected Mac and iPhone to the same Wi-Fi
• change the iPhone Wi-Fi setting, set http proxy to manual and change the Server to you Mac ip address and setting the Port. My Port is 80.

• you can input http://<Mac ip>:<your customer server port> in iPhone's safari

Found it in the manual

The mode parameter is used to specify the handling of untracked files. It is optional: it defaults to all, and if specified, it must be stuck to the option (e.g. -uno, but not -u no).

git status -uno

If you are using nl2br, all occurrences of \n and \r will be replaced by <br>. But if (I don’t know how it is) you still get new lines you can use

str_replace("\r","",$description);
str_replace("\n","",$description);

to replace unnecessary new lines by an empty string.

Open a separate terminal and start adb with logcat. On my (linux) system;

~/android-studio/sdk/platform-tools/adb logcat

Not sure if you can do this with MySQL, but you can use a CTE in T-SQL

; WITH tmpPeople AS (
 SELECT 
   DISTINCT(FirstName),
   MIN(Id)      
 FROM People
)
SELECT
 tP.Id,
 tP.FirstName,
 P.LastName
FROM tmpPeople tP
JOIN People P ON tP.Id = P.Id

Otherwise you might have to use a temporary table.

With current projects you may want to use the NS_ENUM() or NS_OPTIONS() macros.

typedef NS_ENUM(NSUInteger, PlayerState) {
        PLAYER_OFF,
        PLAYER_PLAYING,
        PLAYER_PAUSED
    };

Best result for me so far:

div to be centered:

position: absolute;
top: 50%;
transform: translateY(-50%);
margin: 0 auto;
right: 0;
left: 0;

the size attribute matters, if the size=5 then first 5 items will be shown and for others you need to scroll down..

<select name="numbers" size="5">
    <option>1</option>
    <option>2</option>
    <option>3</option>
    <option>4</option>
    <option>5</option>
    <option>6</option>
    <option>7</option>
</select>

Try this

#include <stdio.h>

struct context;

struct funcptrs{
  void (*func0)(struct context *ctx);
  void (*func1)(void);
};

struct context{
    struct funcptrs fps;
}; 

void func1 (void) { printf( "1\n" ); }
void func0 (struct context *ctx) { printf( "0\n" ); }

void getContext(struct context *con){
    con->fps.func0 = func0;  
    con->fps.func1 = func1;  
}

int main(int argc, char *argv[]){
 struct context c;
   c.fps.func0 = func0;
   c.fps.func1 = func1;
   getContext(&c);
   c.fps.func0(&c);
   getchar();
   return 0;
}

updated asnwer for those people 'correctly' pointing out it doesnt directly answer the question, more bring an alternative option.

In an async context you could just write the async version in sync method with using the await keyword. You can simply turn the async callback method into an promise like this:

function fileExists(path){
  return new Promise((resolve, fail) => fs.access(path, fs.constants.F_OK, 
    (err, result) => err ? fail(err) : resolve(result))
  //F_OK checks if file is visible, is default does no need to be specified.

}

async function doSomething() {
  var exists = await fileExists('filePath');
  if(exists){ 
    console.log('file exists');
  }
}

the docs on access().

I use the Android KeyStore to encrypt the password using RSA in ECB mode and then save it in the SharedPreferences.

When I want the password back I read the encrypted one from the SharedPreferences and decrypt it using the KeyStore.

With this method you generate a public/private Key-pair where the private one is safely stored and managed by Android.

Here is a link on how to do this: Android KeyStore Tutorial

We tend to get this message when we try to subscribe to a topic that has not been created yet. We generally rely on topics to be created a priori in our deployed environments, but we have component tests that run against a dockerized kafka instance, which starts clean every time.

In that case, we use AdminUtils in our test setup to check if the topic exists and create it if not. See this other stack overflow for more about setting up AdminUtils.

The first thing that comes to my mind is a one-liner regex:

var pageNum = $("#specificLink").attr("href").match(/page=([0-9]+)/)[1];

You could use

protected $casts = [
    'created_at' => "datetime:Y-m-d\TH:iPZ",
];

in your model class or any format following this link https://www.php.net/manual/en/datetime.format.php

Use String#slice, also aliased as [].

a = "hello there"
a[1]                   #=> "e"
a[1,3]                 #=> "ell"
a[1..3]                #=> "ell"
a[6..-1]               #=> "there"
a[6..]                 #=> "there" (requires Ruby 2.6+)
a[-3,2]                #=> "er"
a[-4..-2]              #=> "her"
a[12..-1]              #=> nil
a[-2..-4]              #=> ""
a[/[aeiou](.)\1/]      #=> "ell"
a[/[aeiou](.)\1/, 0]   #=> "ell"
a[/[aeiou](.)\1/, 1]   #=> "l"
a[/[aeiou](.)\1/, 2]   #=> nil
a["lo"]                #=> "lo"
a["bye"]               #=> nil

   @Html.TextBoxFor(model => model.IdUsuario, new { @Value = "" + User.Identity.GetUserId() + "", @disabled = "true" })

@disabled = "true"

Work very well

For rep reasons, I can't add this as a comment (where it would better go with bennedich's answer), but for Windows command line, here is the correct syntax:

curl -u YOUR_USERNAME https://api.github.com/user/repos -d "{\"name\":\"YOUR_REPO_NAME\"}"

It's the same basic form, but you have to use double quotes (") instead of single, and escape the double quotes sent in the POST parameters (after the -d flag) with backslashes. I also removed the single quotes around my username, but if your username had a space (possible?) it would probably need double quotes.

Another solution would be as below where the list is placed under a drop-down button.

  <button class="btn dropdown-toggle btn-primary btn-sm" data-toggle="dropdown"
    >Markets<span class="caret"></span></button>

    <ul class="dropdown-menu", style="height:40%; overflow:hidden; overflow-y:scroll;">
      {{ form.markets }}
    </ul>

None of these answers worked for me, at least not for scrolling down a facebook search result page, but I found after a lot of testing this solution:

while driver.find_element_by_tag_name('div'):
    driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
    Divs=driver.find_element_by_tag_name('div').text
    if 'End of Results' in Divs:
        print 'end'
        break
    else:
        continue
